115 Hybrid Cryptographic Scheme for Data Communication
Download citation file:
In this paper, a new cryptosystem based on hybrid approaches is proposed. This scheme provides multi-security services. The proposed scheme takes the advantage of neural networks computation power to build an encryption algorithm to serve data confidentiality, where the encrypting process is done by used shard key as input to the ANN model, and the data need to be secured will be the output of it, the generated set of weights will act as the cipher. Also, made combination between MAC technique and RSA encryption algorithm produced digital signature of the scheme which provided the integrity and authentication services. The experimental results indicate that the proposed cryptosystem has a high confusion and diffusion properties, therefore it has a high security and it is suitable for secure communications.
